Groomsmen/bridesmaid Pairing

Not weird at all

It would be fine to have them walk down the aisle together. We had married people walk down with single people and all just because they were who we wanted in our bridal party. It's ok whichever way it goes .

I don't think it would be that big a deal. Most everyone knows that there's a very good chance that the bridesmaids are not actually coupled with the groomsmen they walk with; in my wedding's case, that couldn't have been more true as six of our eight attendants were married, and the youngest groomsman was 16 where the bridesmaid he walked down the aisle with was in her 30s. From an aesthetic standpoint, I'd be relieved if that other guy drops out because then you're even! Before you make any changes, though, wait a little longer to see if you hear anything from this wishy-washy guy. He could have a lot going on, or maybe he's unsure of what his role in everything is.

It is not so weird at all to have siblings walk together down the aisle.
